TLTCIFICATION forming part of Letters Patent No. 307,735, dated November4, 1884:.

A pplieation tiled Juize 10, 1F83. (Modehl as shown, for facilitatingthe iiow of ink to the pen, as hereinafter described.

By my invention a fountain-pen composed of but comparatively few partsis produced, and the general construction of this class of pen greatlyimproved and simplified.

The subject-matter claimed as new will be herein after specificallydesignated.

In the accompanying drawings, which illustrate my invention7 Figure l isa longitudinal section of my improved fountain-pen, and Fig. 2 is across-section on the line 2 2 of Fig. 1.

A'teferring to Fig. 1, A represents a barrel o all wim/1t 752'; 71Min/conce/'n.-

Be it known that I, Lnwrs E. WATERMAN,

ner: The downward iiow of the ink by gravity and through the action ofcapillary attraction in the act of writing causes it to pass Vthroughthe groove d, and tends to create avacuum within the reservoir, which ismet by the influx of air passing upward through the groove d. The motioncaused by the receding and advancing of the lower surface of the penfrom and toward the bar O, caused by the ordinary operation of writing,increases the How of ink from the barrel, and permits the steady supplyof the ink to the slot in the pen, from whence it is conveyed to itspoint or tube for containing the ink, and it may be and to the surfacebeing written upon. A cap, formed of rubber or other suitable material.E, is employed for protecting the nib of the A tubular piece, B,preferably of the same i pen when not in use. The cap may be placedmaterial as the barrel A, is shouldered and l upon the extremity of thebarrel when the screw-threaded at b, and is made to iit within l pen isbeing used, and when in such position the correspondiugly-threadedextremity, a, of it serves to lengthen the holder. the barrel A. Thefeed-piece which I employ By my invention I do away with the tubuforconveying theink from the barrelAto the l lar ink-duct usually employedin connection nib of the pen I consists of a bar, C, formed with pens ofthis class, and which has heretoof rubber or other suitable material,having fore been objectionable for the reason, among one extremity, c,tapering conically from one others, that it is very liable to conductmore inl; to the nib than is necessary. The gradual side to the otherol' the body O. The other extremity of the body is formed to t tightlydecrease in size toward the nib of the ink-conducting groove in myimproved pen provides within the tubular piece B. The upper side of t-hebar Gis provided with a groove, d, exagainst the excessive flow of ink,which by tending throughout its entire length, and comreason of a largeportion of the groove being munieates with the ink-reservoir in the samein direct contact with the pen a sufficient ]ilane-that is, withoutleaving the surface of quantity of ink is supplied.

I form one or more verynarrow scribed herein, as it is obvious that the same slits or fissures,c e, (see Fig. 2,) longitudimay be modified without departing from theprinciples of my invention.

The form of the ink-duct may be modified, l and, instead of one groovebeing formed in its l upper surface, several maybe employed, and l thenumber and'size of the fissures in said groove or grooves may-be varied,if desired.

I am aware that fountain-pens have heretohaving a groove in its surfacenext to the peinand extending part Way of the length ofthe bar, andthence by anvangular orifice into the reservoir; but

such 'construction is defective, as stoppages LEWIS E. WATERMAN.
